Governments can help nudge the industry to use more wood, particularly in the public sector—the construction industry’s biggest client. That would help wood-building specialists achieve greater scale and lower costs. Zero-carbon building regulations should be altered to take account of the emissions that are embodied in materials. This would favour wood as well as innovative ways of producing other materials.

The Economist compares the environmental impact of the industrialized world's most common building materials, cement and steel, with that of carbon-trapping wood, and how an earnest effort to reach the emission goals outlined in the Paris Climate Agreement cannot ignore building with timber on a...

Researchers at Columbia University have invented a digital "wood" using 3D-printing technology to replicate the material's external and internal structure. They believe the technique could be applied to other anisotropic materials, which are especially difficult to replicate due to their... View full entry

London-based designers Rowan Minkley and Robert Nicoll along with research scientist Greg Cooper have developed a biodegradable alternative to resin-based building materials such as low- and medium-density fiberboard. Called Chip[s] Board, the new material is made from non-food-grade industrial potato waste and is free of toxic chemicals and formaldehyde.

Potatoes are truly the most versatile vegetable. Chips, hash browns and vodka are just a few of its miracles, but it has also recently been added to the list of innovative building materials. London-based designers Rowan Minkley and Robert Nicoll, along with research scientist Greg Cooper, have... View full entry

Students at the University of Cape Town have developed a bio-brick that mixes sand, bacteria and human urine. Unsurprisingly, it is the world's first building material to be made from the liquid waste high in nitrogen and phosphorous. The brick is created through a process called microbial...

Researchers say India could alleviate its growing shortage of sand, which is needed for concrete, by partially replacing it with waste plastic.

Research carried out by the University of Bath in the UK, and India’s Goa Engineering College, has found that concrete made with an admixture of ground-up plastic bottles is almost as strong as traditional concrete mixtures.

With India's rapid urbanization, concrete construction has dramatically increased causing a shortage in the country's sand used to make the building material. Mixing in plastic bottles focuses on solving both the issue of a sand shortage and the accumulation plastic waste on the streets. While... View full entry

Follow the intricate supply chains of architecture and you’ll find not just product manufacturers but also environmental polluters. Keep going and you’ll find as well the elusive networks of political influence that are underwritten by the billion-dollar construction industry.

In "What You Don't See," Brent Sturlaugson examines the supply chains of architecture to make the case that designers must expand their frameworks of action and responsibility for thinking about sustainability. Unraveling the networks of materials, energy, power, and money that must be... View full entry

Wang Shu and his wife, Lu Wenyu, of China’s Amateur Architecture Studio want to protect Chinese culture and history by returning to artisanal building techniques and the use of materials such as natural stone, wood and bamboo. Wang Shu’s rejection of what he calls “professional, soulless architecture” has almost become a war cry. That kind of architecture, he believes, is ruining China.

Amateur Architecture Studio focuses on creating work that transcends the black and white divide of traditional and modern architecture. The duo have made it their mission to bring back handmade work and natural materials into modernization. China Academy of Art Xiangshan Campus by Amateur... View full entry

Earlier this week, the Oregon Building Codes Division announced a statement of alternate method (SAM) that makes Oregon the first state to allow for construction of wooden high-rises without special consideration. Previously, Portland, Ore., was the first American city to issue a permit for an all-wood high-rise, Project’s 12-story-tall Framework.

The statement of alternate method (SAM) was developed over two years by a committee created from the International Code Council’s Board of Directors. The committee proposed 14 suggestions concerning cross-laminated timber standards and best-practices, which were all accepted by the Oregon... View full entry

Scientists with the European Space Agency (ESA) have created a terrestrial simulation of moon dust to practice making bricks with. And it appears lunar “soil” is significantly different from its terrestrial equivalent, as it can be crushed, burned and compressed to form building materials, or used as the raw material for 3D printing.

The European Space Agency (ESA) is experimenting with lunar dust as a building material with goals to avoid lifting hefty materials from Earth into space. Lunar dust is electrically charged and primarily composed of basalt (like volcanic rock) with 40% of its mass made of oxygen. ESA is testing... View full entry

Cut peat blocks were already being used for building houses thousands of years ago. Now, scientists at the University of Tartu have developed a material which could make it possible to print energy-efficient houses out of milled peat and oil shale ash using a 3D printer.
— Research in Estonia

"As peat and oil shale ash are not very expensive, house builders would be especially happy about the price of the material. According to Liiv, scientists calculated that the cost for the construction of a house shell printed from this material with a floor surface of 100–150 square meters could... View full entry

Inspired by the work of inventor Philip Ross and his company MycoWorks, Maurer argues that one of the keys to addressing Cleveland’s housing crisis lies in an unlikely source: mushrooms. Specifically, in using mycelium – the vegetative part of a fungus – and Cleveland’s other “natural” resource, construction waste, in a process called “biocycling”, which essentially recycles old buildings into new ones using plant materials.

“I like to refer to Cleveland as ‘ground zero’ for biocycling,” says Maurer, who believes the city has the perfect conditions and challenges to serve as a prototype for the process. Cleveland architect Christopher Maurer of Redhouse Studio argues how mycotecture (architecture that uses... View full entry

According to the CDP report, the cement industry is the second-largest industrial emitter of carbon after the steel industry. And when accounting for its use in human-made structures, it is responsible for more than a third of the world’s carbon emissions. But unlike the transportation sector, in which a new type of fuel can dramatically decrease the sector’s pollutants, cement’s problem is, well, cemented in its formulation [...]

Spider silk has long held the title of strongest natural biomaterial, so scientists have been trying to harness it, mimic it and even improve on the recipe for years. Now, researchers at the KTH Royal Institute of Technology have developed a new biomaterial out of wood nanofibers that steals the strength record.
— New Atlas

A new material called "super wood" is eight times stiffer than silk, which has been considered one of the strongest bio-based materials. KTH researchers found a new technique to "densify" wood where fibers assemble to make the cell walls stiff and strong, a process called cellulose nanofibrils... View full entry
